Antenna is a means for radiating or receiving or transmitting energy an antenna is used in an advanced wireless system is usually required to optimize the radiation energy in same direction and suppress it in others. A microstrip patch antenna, also referred to as patch antenna is a narrowband, widebeam antenna fabricated by etching the antenna element patch in metal trace bonded to an insulati...

In this paper, analyses and design of slotted Rectangular patch antenna for high speed wireless local area network at 5-6 GHz frequency has been done. A parametric study of the antenna has been carried out, to analyze and understand the effects of dimensional parameters. Main disadvantage of the microstrip patch antenna is its narrow bandwidth. However, in this paper slotting technique has been...

Broadband frequency of operation demonstrated by single geometry .for broadening the bandwidth and maximum directional gain (6.6dBi 8dBi) gap-coupled multi-resonator loaded on parasitic and active patch. The geometry of a single probe fed rectangular Micro-strip antenna incorporating a slot and gap coupled with parasitic and ac...

In this paper a spirally slotted micro strip antenna with improved bandwidth for lower C band (4-6 GHz) applications was designed and fabricated. The reflection coefficient at the determined position of the proposed antenna was well below −10 dB for the whole frequency band. The size of the antenna was thus reduced by about 62% when compared to a conventional micro strip patch antenna. The band...

In this paper, a compact UWB printed monopole antenna design is proposed. The monopole antenna has the form of an E-shaped structure printed on a substrate with relative dielectric constant of 3.38, and thickness of 1.52mm. The matching through the UWB response is satisfied using a reduced ground plane. The proposed antenna is fed by a 50 Ω unsymmetrical microstrip line. The ground plane is pri...

AbstractThis letter represent a symmetrically notch loaded stacked circular half disk patch antenna. It is found that the bandwidth of the antenna depends directly on the notch dimensions. Bandwidth of the notch loaded stacked circular half disk patch is found to be 44.56 %. This antenna can be applicable for Wireless Local Area Network and ISM Band. Two parallel notches are incorporated to per...

In this paper, a microstrip transmission line combined with a new U-headed dumb-bell defected ground structure (DGS) is investigated. The proposed DGS of two U-shape slots connected by a thin transverse slot is placed in the ground plane of a microstrip line. A finite cutoff frequency and attenuation pole is observed and thus, the equivalent circuit of the DGS unit can be represented by a paral...

This paper presents a 1×4 array antenna using asymmetric T-shaped slit loaded microstrip antenna (MSA). The antenna consists of four MSAs align vertically on a dielectric substrate and ground plane. This antenna will be utilized in WLAN applications as the commercial panel antenna. A modified array configuration is proposed to further enhance the antenna radiation characteristics and usable ban...

The design of array antenna is vital study for today’s Wireless communication system to achieve higher gain, highly directional beam and also to counteract the effect of fading while signal propagates through various corrupted environments. In this study, the design and analysis of a (2x2) microstrip patch antenna array is introduced. It is designed to function in the 5.25 GHz which corresponds...

The on chip spiral inductors are one of the key components in the development of the RFIC‟s as they determine the performance of the circuits such as VCO, LNA, mixers etc. In this paper, the design of an inductor for GaN based RFICs operating in C-band is presented. Sapphire (Al2O3), which is a common substrate for GaN, is used as substrate and silicon nitride (Si3N4), which is a common passiva...
